   Sammanfattning : Kiln drying is the most energy-consuming operation in the industrial production of sawn timber and optimising the process is necessary to improve its efficiency. A key to achieving this is to speed up the drying, but this must not come at the cost of deteriorating the quality of the sawn timber. LÄS MER
